Udemy – ASME B31.3 Process Piping Design — Code, Design & Exam Prep

ASME B31.3 is the code that governs process piping design across oil and gas, chemical, petrochemical, and pharmaceutical plants worldwide. Every wall thickness calculation, every flange rating decision, every pressure test, and every weld examination in process piping comes back to this standard. This course teaches you to use it — not just to know it.

What You Will Learn:

• Navigate ASME B31.3-2022 confidently — scope, fluid categories, key definitions, and the relationship to ASME B31.1, B31.4, and B31.8
• Perform pipe wall thickness calculations using the Clause 304.1.2 equation and select the correct pipe schedule — the most tested B31.3 topic in both the API 570 and PE exams
• Read ASME B16.5 pressure-temperature rating tables and determine the correct flange class for any design condition
• Select materials from Appendix A, determine allowable stresses, establish minimum design metal temperature (MDMT), and specify impact testing requirements
• Calculate branch reinforcement using the Clause 304.3 area replacement method — and know when integrally reinforced fittings are a better solution
• Assess piping flexibility using the Clause 319.4 displacement stress range equation, apply the simplified L/U criterion, and size expansion loops
• Specify examination requirements by fluid category — from Category D visual-only through Category M and High-Pressure 100% examination — and select the correct NDE method
• Calculate hydrostatic and pneumatic test pressures, manage test documentation, and understand the full B31.3 pressure testing sequence
• Apply pipe support requirements under Clause 321 and use the support span calculation to avoid excessive deflection and overstress
• Tackle API 570 and PE exam B31.3 questions using three fully worked exam scenarios with model answers and examiner commentary
